内镜超声在诊断和治疗肝脏疾病中的价值

Value of Endoscopic Ultrasonography in the Diagnosis and Treatment of Liver Diseases

肝脏疾病的传统影像学诊断方法主要包括B超、CT、MRI等,内镜超声（EUS）以往较少用于肝脏疾病的诊断.近年,EUS和EUS-细针穿刺活检（FNA）在肝脏疾病的诊断中取得了较大进展,对B超、CT、MRI难以发现的微小病变有一定诊断价值,且EUS-FNA可获得较好的组织学和细胞学标本,有助于明确微小病变的性质.本文就EUS和EUS-FNA在肝脏疾病,尤其是肝癌诊断中的价值作一综述,旨在提高医师对两者临床应用的认识.

The diagnosis of liver diseases was traditionally performed by ultrasound, CT or MRI, while endoscopic uhrasonography （EUS） was used unusually. However, in recent years EUS and EUS-fine needle aspiration （EUS-FNA） developed rapidly, and were used for the diagnosis of various liver diseases that could not be detected by ultrasound, CT or MRI. Through EUS-FNA, satisfactory liver specimens could be obtained and the nature of some minute liver diseases could be defined clearly. This article reviewed the clinical significance of EUS and EUS-FNA in the diagnosis of liver diseases, especially liver cancer, for promoting their clinical application.
